integral from 0 to pi/3 of 3sin(x)

\int_{0}^{\frac{π}{3}} 3 sin (x) d x

\frac{3}{2}

Decimal

1.5

Solution steps

\int_{0}^{\frac{π}{3}} 3 sin (x) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 3 \cdot \int_{0}^{\frac{π}{3}} sin (x) d x

Use the common integral:

\int sin (x) d x = - cos (x)

= 3 [- cos (x)]_{0}^{\frac{π}{3}}

Compute the boundaries:

\frac{1}{2}

= 3 \cdot \frac{1}{2}

Simplify

= \frac{3}{2}

\int_{1}^{3} \frac{1}{( x + 1 ) x} d x

\int_{1}^{8} \frac{12 x}{x ^{2} + 6} d x

\int_{1}^{2} (2 x + 4) d x

\int_{0}^{a} x d x

\int_{0}^{1} (e^{2 x}) d x
